Earlier today, I replaced the RAM in my blackbook from the standard one that came with it to some crucial approved DIMMs. I followed the instructions, and put it in, and put the L bracket back in its spot. I noticed that it seemed to bloat where the dims were, where as when I first opened it it was completely flat. Still, my battery went in fine, and I proceeded to turn my mac back on. When I hit the power button, it made the sound that it makes every time I turned it on or woke it up (my thought would be the hard drive spinning, but not sure, I am not talking about the dong that all macs make though). IT sat there with its light on, but nothing shows up on the screen, no dong or anything. went back and put the old ram in, still the same thing. Now I noticed, that the dimms didn't click into place like they have for all the windows laptops I've worked with, rather they seem to just drop in to place, and are held there by that L bracket. Am I doing somehting wrong here? Is my problem I just havent installed something right, or have I really gone and screwed something up.
